XtResolvePathname(3Xt)	XT FUNCTIONS	XtResolvePathname(3Xt)

NAME
       XtResolvePathname - search for a file using standard sub-
       stitution

SYNTAX
       String XtResolvePathname(display, type, filename, suffix,
       path, substitutions, num_substitutions, predicate)
	     Display *display;
	     String type, filename, suffix, path;
	     Substitution substitutions;
	     Cardinal num_substitutions;
	     XtFilePredicate predicate;

ARGUMENTS
       display	Specifies the display to use to find the lan-
		   guage for language substitutions.

       type
       filename
       suffix	Specify values to substitute into the path.

       path	Specifies the list of file specifications, or
		   NULL.

       substitutions
		   Specifies a list of additional substitutions
		   to make into the path, or NULL.

       num_substitutions
		   Specifies the number of entries in substitu-
		   tions.

       predicate   Specifies a procedure called to judge each
		   potential file name, or NULL.

DESCRIPTION
       The substitutions specified by XtResolvePathname are
       determined from the value of the language string retrieved
       by XtDisplayInitialize for the specified display.  To set
       the language for all applications specify ``*xnlLanguage:
       lang'' in the resource database. The format and content
       of the language string are implementation-defined.   One
       suggested syntax is to compose the language string of
       three parts;  a	``language  part'',  a ``territory
       part'' and a ``codeset part''.  The manner in which this
       composition is accomplished is implementation-defined and
       the Intrinsics make no interpretation of the parts other
       than to use them in substitutions as described below.

       XtResolvePathname calls XtFindFile with the following sub-
       stitutions in addition to any passed by the caller and
       returns the value returned by XtFindFile:

       %N   The value of the filename parameter, or the

	    application's class name if filename is NULL.

       %T   The value of the type parameter.

       %S   The value of the suffix parameter.

       %L   The language string associated with the specified
	    display.

       %l   The language part of the display's language string.

       %t   The territory part of the display's language string.

       %c   The codeset part of the display's language string.

       %C   The customization string retrieved from the resource
	    database associated with display.

       %D   The value of the implementation-specific default
	    path.

       If a path is passed to XtResolvePathname, it will be
       passed along to XtFindFile.  If the path argument is NULL,
       the value of the XFILESEARCHPATH environment variable will
       be passed to XtFindFile. If XFILESEARCHPATH is not
       defined, an implementation-specific default path will be
       used which contains at least 6 entries.	These entries
       must contain the following substitutions:

       1. %C, %N, %S, %T, %L	or%C, %N, %S, %T, %l, %t, %c
       2. %C, %N, %S, %T, %l
       3. %C, %N, %S, %T
       4. %N, %S, %T, %L   or	%N, %S, %T, %l, %t, %c
       5. %N, %S, %T, %l
       6. %N, %S, %T

       The order of these six entries within the path must be as
       given above.  The order and use of substitutions within a
       given entry is implementation dependent. If the path
       begins with a colon, it will be preceded by %N%S.  If the
       path includes two adjacent colons, %N%S will be inserted
       between them.

       The type parameter is intended to be a category of files,
       usually being translated into a directory in the pathname.
       Possible values might include ``app-defaults'', ``help'',
       and ``bitmap''.

       The suffix parameter is intended to be appended to the
       file name.  Possible values might include ``.txt'',
       ``.dat'', and ``.bm''.

       A suggested value for the default path on POSIX-based sys-
       tems is

	      <XRoot>/lib/X11/%L/%T/%N%C%S:<XRoot>/lib/X11/%l/%T/%N%C%S:\
	      <XRoot>/lib/X11/%T/%N%C%S:<XRoot>/lib/X11/%L/%T/%N%S:\
	      <XRoot>/lib/X11/%l/%T/%N%S:<XRoot>/lib/X11/%T/%N%S

       where <XRoot> is replaced by the root of the X11 installa-
       tion tree (/usr/X11R6, for example).

       Using this example, if the user has specified a language,
       it will be used as a subdirectory of <XRoot>/lib/X11 that
       will be searched for other files.  If the desired file is
       not found there, the lookup will be tried again using just
       the language part of the specification.	If the file is
       not there, it will be looked for in <XRoot>/lib/X11.  The
       type parameter is used as a subdirectory of the language
       directory or of <XRoot>/lib/X11, and suffix is appended to
       the file name.

       The %D substitution allows the addition of path elements
       to the implementation-specific default path, typically to
       allow additional directories to be searched without pre-
       venting resources in the system directories from being
       found.  For example, a user installing resource files
       under a directory called ``ourdir'' might set XFILESEARCH-
       PATH to

	      %D:ourdir/%T/%N%C:ourdir/%T/%N

       The customization string is obtained by querying the
       resource database currently associated with the display
       (the database returned by XrmGetDatabase) for the resource
       application_name.customization, class applica-
       tion_class.Customization where application_name and appli-
       cation_class are the values returned by
       XtGetApplicationNameAndClass.  If no value is specified in
       the database, the empty string is used.

       It is the responsibility of the caller to free the
       returned string using XtFree when it is no longer needed.
